Mercedes-Benz G580 vs Cupra Leon

What's the difference?

As per the 1979 original, the current G-Class is produced by Magna Steyr in Arnie’s home town of Graz in Austria. And many fundamental things haven’t changed since then. But clearly this EV monster’s exotic electric powertrain is a huge departure.

It retains impressive off-road ability and straight-line speed. But will it hit the mark with top-end luxury 4WDers? Short story, this thing is wild, and it will be irresistible for a likely narrow band of tech-focused ‘must have the latest and greatest’ buyers. Nothing like impressing friends and family with a tank turn.

The Cupra Leon VZe demands you give it an appropriate amount of time to get to know.

Because, as an unknown challenger brand, as a hatch in an SUV world, as a PHEV wearing an EV price tag, it is up against it. And it's too interesting a car to be summarily dismissed.

But as long as you're not expecting a pure hot-hatch-cum-ultra-economical eco warrior, the VZe is a close-enough approximation of both for it to be an intriguing and enjoyable multi-faceted small car, while also possessing a fair degree of space as well as styling flair.

If you can forgive the screwy multimedia and cope with the high pricing, there's a lot to love here.

Okay, so Mercedes-Benz says, with a straight face, that “with the aim of optimising the vehicle’s aerodynamics” classic G-Class elements have been revised, including the reprofiled bonnet, ‘air curtain’ vents in the flares over the rear wheel arches, A-pillar cladding and the small spoiler on the edge of the roof.

At the same time, the 20-inch wheels are also claimed to be "aerodynamically optimised” and underneath, a 26mm underbody casing made from a mix of materials, including carbon-fibre (attached to the ladder frame with more than 50 steel screws), protects the battery from dust, dirt and rocks.

In ticking off the Edition One, car-spotters should look for black rims with blue brake callipers behind them, blue inserts in the exterior protective strips as well as black door handles and a new rectangular design box on the rear door for storing items such as charging cables, tools or snow chains. If you want a spare wheel, choose the standard model.

An optional black-panel radiator grille ($3800) features tinted lighting units as well as an animated LED light band and chrome surround. The light band can be activated as a running light or an animation when locking and unlocking the vehicle.

And it’s worth noting Mercedes-Benz and the car’s contracted manufacturer, Magna Steyr, have invested much time and many Euros in retaining the car’s classic handle and door lock design. G-Wagen owners will recognise its sound from several kilometres away.

Inside the G580 it’s clear this is one area where the G-Class has progressed enormously over the decades. It’s still quite upright in terms of the dash design, but you’re confronted by twin 12.3-inch screens, supporting the Mercedes-Benz user interface. 

All very high-tech, but that’s balanced by an old-school grab-handle for the front passenger to latch onto during off-road work. 

The signature turbine-style air vents are located within squared-off panels, and in the limited Edition One you have a blue fleck running through carbon-fibre inserts on the centre console, door cards and that front grab handle. In the standard car it’s a (very attractive) walnut open-pore wood rather than carbon.

A luxurious interior for sure.

One reason why you might want a Leon over, say, one of the more common PHEV SUVs like the Mitsubishi Eclipse Cross PHEV, or even Cupra's own Formentor PHEV, is because of its pleasing, conventional five-door hatchback size and shape.

Sleek and chiselled, it is quite a looker, especially from the rear three-quarter view. And the wheels are equally pretty.

Only from front-on does the Leon seem anonymous and somewhat dated in appearance. But at least it avoids the droopy fussiness of the 308.

For the record, the G63 is just over 4.6m long and a little more than 1.9m wide with a 2890mm wheelbase. So, not huge, but its close to 2.0m height is hard to ignore. 

In the front there’s lots of breathing space, and in terms of storage you have generous bins in the doors with plenty of room for big bottles. Then there’s a centre armrest, which doubles as the top of a deep storage box housing a USB-C port inside. 

A sliding roller cover in the centre console reveals two cupholders, another two USB-C sockets, a 12-volt outlet and a wireless charging pad. Add in a big glove box and you’ve got plenty of options in terms of storage, power and connectivity. 

In the back, sitting behind the driver’s seat set for my 183cm position I’ve got tons of foot and legroom and, no surprise, lots of headroom.

There’s a fair bit of sculpting in the rear seat, which is as nice as it is unusual (makers often avoid bolsters on the rear seat as it makes the backrest harder to fold flat). And in terms of three-abreast accommodation, a smaller adult will be okay in the centre spot for shorter journeys. Three up to mid-teenage kids will be swimming in it.

Then, for practicality you again have generous bins in the doors. And if you need even more capacity, fold down the centre armrest which houses two different size cupholders. 

In the rear of the centre console you’ve got two USB-Cs, a 12-volt power outlet, individual climate control and directional vents.

There are map rockets on the front seatbacks and more air vents in the B-pillar. So, when it comes to comfort, powering up devices and storing ‘things’ you’re well taken care of.

The side-opening tailgate door opens from right to left, which isn’t ideal when parallel parked on the left hand side of the road, but boot volume is over 600 litres (VDA) with all seats upright, expanding to nearly 2000 litres with the 60/40 split-folding rear seat lowered.

There are multiple tie-down hooks, a netted pocket, two lights, a 12-volt outlet as well as a ‘ski-port’ door and sliding cargo cover to enhance practicality and security.

As mentioned earlier, the full-size spare in the standard model, but the Design Box replaces it on the Edition One, although Mercedes-Benz says it’s aiming to make a spare available as an option later in the year.

Once standard setters, VW interiors have copped flak lately, losing the lead they once enjoyed in terms of perceived quality and functionality. A big backward step.

Within this context, the Leon's cabin is as aesthetically appealing as the exterior's, with lots of interesting angles and textures set within a broadly familiar VW-corporate multi-level dashboard design and presentation.

Most of the basics are largely fine, too. From the superbly enveloping front bucket seats and commanding driving position, to excellent ventilation and plenty of storage, there's much to commend.

The same goes for the moody, techy ambience, though it's closer to ‘chilled Audi' than ‘zesty Latin' in flavour.

Directly ahead of the driver is a 10.25-inch instrument cluster, offering several combinations of vehicle speed/operation and multimedia views.

Some of it looks good, some suffers from info-overload, but at least it's all configurable. Pick your favourite. And build quality seems up to scratch, too.

Like the Golf, there's also above-average space for longer legs and outstretched arms, while – after having to duck down a bit to get in – head and shoulder room are sufficient.

Selecting gears is a matter of manipulating a charmless stubby toggle. It works well enough, but remember when VW Group owners could interact with a Tiptronic-style lever and feel more immersed in the driving process? Memories.

That's replaced by paddle shifters, a divisive substitute that's of debatable merit in an electrified vehicle such as this, since they would serve better as regenerative braking controls.

But that's only the beginning of the confusion that ensues in the Cupra.

Reach for the 12-inch touchscreen to scroll through your many and varied media options, try and figure out the trip computer or search for an odometer reading, and any goodwill earned will be severely curtailed by just how needlessly complicated these and other once-simple tasks have become.

Plus, frustratingly, our particular car's multimedia system would just switch off mid-operation. This is not good.

We're certain time and familiarity will help make sense of working out where everything is and how to access vehicle functions located within layers of that touchscreen's myriad menus, but it is distracting and complicated.

And how is it that we could not find how to switch on nighttime illumination for the climate controls? In a week we failed to find that answer. And who ever green-lit fiddly slide controls over good old buttons? It's maddeningly frustrating.

Moving to the back seat, the Leon makes up some ground.

Two larger adults should settle into the outboard positions comfortably and snugly, aided by a pair of rear-facing air vents accompanied by a climate-control panel, two USB-C ports, a folding centre armrest with cupholders, ski-port access to the boot and useful storage via door bins and map pockets. There's even enough space for a third, smaller passenger to squeeze in between.

Further back, while the boot floor is long and flat and with a large tailgate opening to aid loading stuff in and out, the actual cargo capacity is just 270 litres, or nearly one-third down on the regular petrol Leon grades' 380L offering. This is due to the battery pack and related EV gubbins.

Speaking of which, if you need to carry charging cables there's nowhere to properly store them other than in the main boot area. And don't forget, there's no spare wheel.

At least there's a sturdy parcel shelf to keep prying eyes from seeing what you're carting around.

The VZe's interior, then, is spacious and broadly sensibly executed, but is let down – and mostly unnecessarily so – by some of the details. We strongly recommend trying before buying.

There's lots to unpack here.

SEAT started in 1950 as a venture between Fiat, the Spanish government and some private banks, until VW took over in 1986 and turned it into a youth-baiting value brand. Think pre-current Kia positioning.

Meanwhile, Cupra ­– a portmanteau of Cup Racing – had began as SEAT's competition arm earlier that decade. And there's been a Leon (referencing both ‘lion' and a city in Spain) based on every Golf since the latter's Mk4 iteration, making this generation numero cuatro.

Halve that figure and you end up with the number of small-car PHEVs left in Australia – Cupra's and another big-cat evoking Euro, the Peugeot 308 GT Sport PHEV, costing a few grand more than the VZe from $64,990, before on-road costs.

These high prices are clearly hurdles for Australian small-car buyers. Even Mercedes-Benz recently axed the slow-selling A250e due to a lack of buyer interest. Kia dropped the Niro PHEV. And Hyundai canned the Ioniq PHEV.

So, why are these types of cars so expensive, then?

The Leon and 308 feature a turbo-petrol engine, backed up by a small motor and a battery pack that's large enough to provide a claimed 67km of electric-only range in the Cupra's case. On paper at least.

That's more than the cheaper non-plug-in hybrid alternatives like the wildly-popular Toyota Corolla and superb Honda Civic e:HEV can manage.

So, besides exclusivity and two powertrains, what does the Leon VZe give you for your circa-$65K drive-away ask?

On the safety front, you'll find the now-usual driver-assist items like autonomous emergency braking (AEB), lane-support systems and adaptive cruise control, as well as 10 airbags including a nifty front-centre item. More on this in the safety section below.

Buyers also score LED headlights, auto high beams, fog lights with cornering function, adaptive dampers, tyre-pressure monitors, a reverse camera, electronic instrumentation, three-zone climate control, variable-ratio steering, keyless entry/start, satellite navigation, wireless phone charging as well as wireless Apple CarPlay/Android Auto.

There's also rear privacy glass, four USB-C ports, sports front seats, a heated steering wheel, paddle shifters, ambient lighting, powered/heated exterior mirrors as well as 19-inch alloy wheels and a tyre repair kit. No spare wheel is offered.

The pricier 308 PHEV has most of these plus Matrix LED lighting, Nappa leather upholstery, panoramic opening sunroof, heated/massaging front seats, 360-degree surround-view vision and a digital radio, but has smaller (18-inch) alloys and no adaptive dampers.

Our test car was fitted with the 'Leather Package' that adds $2050 to the price, ushering in leather upholstery, heated front seats with driver's side power and memory, premium audio and dash-top stitching, while the sunroof costs $1800 more.

These take the VZe north of $65,000 drive-away. That's pure-EV territory. Little wonder buyers baulk at PHEV small cars in Australia.

The G580 is powered by four permanently excited synchronous motors, each delivering around a CLA200’s worth of power and torque to each wheel for overall outputs in excess of 432kW/1164Nm.

Each motor has its own two-stage transmission and power electronics for almost infinite fine-tuning of the direction and amount of drive sent to individual wheels. Merc calls it ‘individual-wheel drive’.

Under the Leon VZe's bonnet is a variation of the German parent brand's familiar 1395cc 1.4-litre direct-injection four-cylinder turbo-petrol engine, driving the front wheels via a six-speed dual-clutch transmission.

This Euro 6-rated unit produces 110kW of power between 5000-6000rpm and 250Nm of torque from 1550-3500rpm.

Meanwhile, the 85kW/330Nm electric motor also nestled under there is fed by a 12.8kWh Lithium-ion battery pack slung out back. The system outputs combined produce 180kW and 400Nm.

Weighing in at 1634kg (tare), the VZe's power-to-weight ratio is an impressive 110kW per tonne, explaining this portly small car's feisty 6.7 second dash in the 0-100km/h sprint. However, once the battery is depleted, that drops to a much-more mundane 67.3kW/tonne.

Based on VW's 'MQB Evo' modular transverse engine architecture, the Leon features a sports-tuned MacPherson-style strut set-up up front and a multi-link rear end, while adaptive dampers and variable-ratio electric power steering are also fitted.

Housed in a torsion-resistant casing and embedded low down in its ladder-frame chassis, the G580’s 116kWh two-tier, liquid-cooled lithium-ion battery pack delivers a WLTP-rated range of 473km, or 567km on the more lenient NEDC scale.

‘Eco Assistant’ and ‘Range Monitoring’ functions provide continuous information on battery status, energy consumption and estimated range.

Maximum system capacity is 400 volts which enables 200kW DC charging, meaning a 10 to 80 per cent fill in as little as 32 minutes. Maximum AC charging capacity is 11kW.

Claimed energy use is 23.1kWh/100km, and we saw an average of 28.6kWh across urban and highway running on the launch drive program.

Not exactly a ‘green’ EV choice, then, but it’s worth noting a one-year Chargefox subscription is included to off-set the car’s energy appetite.

Cupra says the combined cycle average fuel consumption figure is a startling 1.8 litres per 100km, equating to just 40 grams per kilometre of carbon-dioxide emissions. The electricity consumption claim is 11.2kWh/100km.

Out in the real world, we averaged 5.9L/100km pump-to-pump, while the car's trip computer read 5.5L. This is a disappointment.

It must be all those extra kilos the VZe has to carry around, as most of our driving was inner-urban or casual freeway cruising. The stop/start system was working overtime once that battery depleted.

We managed fewer than 40km of pure-electric driving, against a WLTP rating of 52km (or 67km using the more-lenient NEDC number Cupra quotes), with the trip computer telling us we were averaging 5.9kWh/100km – a figure likely achieved in hybrid mode with the petrol engine chiming in.

Charging times vary, with the 12.8kWh battery needing between six and eight hours plugged in at home, or about four hours using a 7.0kW AC charger via the Type 2 connector. No DC rapid charging ability is available.

Filling up the 40L fuel tank with the required 95 RON premium unleaded petrol and giving the VZe the benefit of the doubt by using the official fuel consumption average of 1.8L/100km to find out its PHEV range, you could theoretically achieve 2220km between refills.

Or about one-third of that by our real-world experience.

So, with 432kW and around 1160Nm, even though the G580 weighs in at around three tonnes, you’re talking 0-100 km/h in 4.7 seconds. And this car gets up and goes… like a beast.

What you don’t get is that traditional Merc-AMG G63 V8 rumble, because, of course, no engine. 

But you do get what Mercedes calls ‘G-Roar’, essentially a sound bar at the front of the car also using the audio system inside to give it what is not exactly an engine noise but some sense of the car progressing. And you can turn it off for completely silent running.

‘Electric Dynamic Select’ changes the parameters of the motors, transmission, suspension, ESP and steering as required. On-road that means ‘Comfort’, ‘Sport’ and ‘Individual’ modes, with off-road comprising ‘Trail’ and ‘Rock’. In the Comfort setting drive flows primarily to one axle for optimum energy efficiency.

Suspension is by double wishbones at the front and a De Dion-style live (rigid) axle at the rear. You’ve got the same adaptive-type set-up as per other G-Class models, so ‘Comfort’ and ‘Sport’ modes and of the many traditional G-Class traits this car exhibits, ride quality is one of them.

Even in Comfort you’ll find even little bumps and thumps making their way up into the seat of the pants and the cabin. It is after all a body-on-frame, ladder-chassis type vehicle and that’s not unusual.  

In terms of steering, it’s accurate and road feel is good. You’ve got 275-wide Falken Azenis FK520 tyres that are more on- than off-road focused. The car feels stable and nicely planted on the road.

The physical brakes are by ventilated discs front and rear, and the big rotors are the same size (353mm) all around. They work nicely and feel like a conventional set-up.

Regenerative braking kicks in as soon as you lift off the accelerator pedal. The powertrain is harvesting energy as the car decelerates and there are four levels you can adjust with the steering wheel paddles up to a quite aggressive level - not quite, but close to a single-pedal set-up.

Off-road, the G580’s ‘G-Steering’ system allows the wheels to turn at different speeds to induce slight ‘drift-like’ oversteer and tighten the turning circle. It works beautifully and the car’s fording depth is 850mm, a full 150mm more than internal-combustion G-Class models.

A three-speed off-road crawl function is adjustable to speeds as low as 2.0km/h, and the car is claimed to remain stable on sideways slopes up to 35 degrees. 

Torque vectoring is used to create ‘virtual diff locks’ and there’s a ‘low-range’ setting. Switch to the ‘Offroad Cockpit’ and data including gradient, lateral inclination, compass readings, tyre pressures and the selected G-Mode appear.

A ‘Transparent Bonnet’ function creates a virtual view of what’s approaching and passing under the front wheels to help the driver pick their way through steep ascents or declines.

For the record, the G580’s approach angle is 32 degrees, departure is 30.7, breakover is 20.3 and ground-clearance is 250mm.

And of course, with the wheels independently powered, the G580’s signature move is what Mercedes-Benz calls a ‘G-Turn’ but the rest of the world calls a tank turn.

If you encounter an obstacle that makes forward progress impossible, the system spins the left- and right-hand wheels in opposite directions so this brute can turn on the spot like an M1 Abrams. You can’t help but crack up laughing when executing this extreme party trick!

In terms of miscellaneous observations around ergonomics and the car in general, it has a 13.6-metre conventional turning circle. So if you’re not using the G Turn function in the car park be ready for a sizeable turning arc.

Also, those aero tweaks here and there seem to have had an effect. Wind noise, especially for such an upright, squared-off design is surprisingly modest. And overall, from a build point of view, this car feels as though it’s been carved from a solid piece of metal. In every aspect it presents as a quality item.

There aren't many PHEVs out there, and that may remain the case, for Australians at least.

But the Leon VZe is definitely one of the more enjoyable of the breed to drive and ride in, with a sporty bias that lives up to its sleek and sexy styling.

With a fully-charged battery, off-the-line acceleration is brisk, and remains rapid as the revs and speed rise. It's smooth and slick in the best VW Group manner, and is accompanied by an appropriately stirring exhaust note. Especially in racy 'Cupra' mode.

The extra torque provided by the electric motor is also felt at low speeds, with little hesitation or delay from the throttle and DCT if the driver wants to instantly plug gaps in traffic.

Expertly tuned, the Cupra ought to be commended for how well-modulated everything feels and responds.

Find a fast, curvy ribbon of road and the Leon's steering comes alive, providing plenty of feel and control, backed up by a taut and agile chassis tune. Whether in 'Comfort' or 'Sport' modes, this is an athletic little hatch.

What the VZe isn't is a hot hatch.

When pushed, even in Sport or Cupra mode, it feels far heavier and less zippy than, say, a Golf GTI, lacking the latter's lithe spirit and dynamic dexterity.

That's not to say the Cupra isn't an involving, capable and secure handler or road-holder, because in isolation this is a terrific little car to hammer along. But it doesn't excite or thrill like the best of them. For more clarity on this, please drive a Civic Type R.

The driver can switch between electric, hybrid and turbo-engine-only modes to help preserve electricity, but once the battery is spent, there isn't the same level of punchy torque available.

Better, then, to instead select Comfort mode and let the adaptive dampers isolate you from those irritating bumps; while not plush, the ride is compliant enough for the VZe to make a very good impression of a grand tourer. Road noise intrusion, too, is pleasingly muted.

We're also grateful Cupra allows the driver to mix-and-match the drive modes, so you can choose a spicy engine tune with cushy suspension if you wish.

Note, however, that our Leon insisted on defaulting to Sport mode after every start-up. Using the flummoxing touchscreen to figure out how to change that to Comfort or Normal was a challenge.

Otherwise, there's much to enjoy from behind the wheel of the VZe. Probably the most fun PHEV we've ever punted around.

Tested in 2021, the Leon range achieved an ANCAP crash-test rating of five stars.

The VZe is fitted with 10 airbags – dual front, side chest, side head, driver knee and a front centre item; the latter is there to help reduce occupant-collision injury in lateral impacts.

On the driver assist tech side of things, the AEB includes pedestrian, cyclist and reversing detection, and there's 'Lane Assist', park assist, blind-spot monitor, rear cross-traffic alert with exit warning, a driver-fatigue monitor, emergency assist and tyre pressure monitors.

The AEB is operational between 5.0km/h and 250km/h. Likewise, the lane-support systems kick in between 65-250km/h.

The VZe is also fitted with electronic stability control, traction control, anti-lock brakes with brake assist and electronic brake-force distribution, adaptive cruise control, an alarm, auto on/off LED headlights with auto high beam, cornering driving lights, front and rear parking sensors, rain-sensing wipers and a rear-view camera.

Plus, the outboard rear seats include ISOFIX child restraint anchors as well as three top tethers for top straps.

The G580 is covered by Mercedes-Benz Australia’s five-year/unlimited-km warranty, which remains the standard offering in the premium part of the market and an eight-year/160,000km drive battery warranty.

Service intervals are every 12 months or 20,000km with service plan pricing available over three ($2645), four ($3980) and five ($4670) years. In approximate terms, each workshop visit will cost ‘around’ $900. Not exactly cheap, especially for an EV, but this is no ordinary electric vehicle.

The Cupra comes with a five-year/unlimited kilometre warranty, which is standard fare nowadays, as well as five years of roadside assistance.

Service intervals are at 12 months or 15,000km.

The VZe is offered with a three-year or five-year service pack in place of capped-priced servicing. The price for three years is $990 (until December 31, 2023).
